Introduction Overview of the Bluetooth wireless technology What is the Bluetooth wireless technology? The Bluetooth wireless technology allows communication between various Bluetooth devices without using cables. Devices which can use this technology include PCs, computer peripheral devices, PDAs, and mobile phones. This omnidirectional communication system enables communication even if the Bluetooth device is in a bag or there are obstacles between the devices. Also, the Bluetooth wireless technology has advanced security functions, such as scrambled frequencies and data encryption. Authentication The authentication routine can block unspecified users' access to this network. When attempting communication with an unregistered Bluetooth device, the devices must first be registered with each other by entering a common passkey to each device. When connecting with a previously registered Bluetooth device, communication starts without entering the passkey. 5-GB
